Impact Air Wrench 1/2" saTra FK-AP7451 — 500 Nm torque

saTra FK-AP7451 is a 1/2" pneumatic impact wrench engineered to deliver up to 500 Nm of torque for fastening and loosening bolts and nuts. The tool operates from standard compressed air systems and uses high-torque impact action to reduce operator effort and speed up assembly and disassembly tasks in automotive, industrial maintenance and workshop environments. Its 1/2" drive size and pneumatic operation make it suitable for repeated heavy-duty use where controlled torque and fast operation are required.

Advantages

The impact wrench provides a balance of high torque output and compact pneumatic design, allowing for efficient bolt removal and installation with reduced manual strain. Its impact mechanism converts air motor power into short, powerful torque pulses for improved performance on stuck or seized fasteners. The 1/2" square drive accepts standard sockets for broad compatibility, and the pneumatic drive ensures continuous operation with appropriate air supply.

Suitable for

• Automotive repair and tyre changing
• Industrial maintenance and machinery service
• Workshop assembly and disassembly tasks
• Hobby mechanics requiring higher torque than hand tools

Key specifications

• Drive size: 1/2" square drive compatible with standard sockets
• Maximum torque: up to 500 Nm
• Power source: pneumatic (compressed air)
• Intended use: fastening and loosening bolts and nuts
• Typical applications: automotive, industrial maintenance, workshops

How to use

Connect the impact wrench to a compressed air supply within the manufacturer's recommended pressure range, and attach an appropriate 1/2" socket for the fastener size. Hold the tool firmly, select the required direction (tighten or loosen), and apply short bursts of operation when dealing with tight or rusted fasteners. For controlled tightening, use incremental bursts and verify torque with a calibrated torque measuring device when precise torque values are required.

Usage recommendations

Use clean, dry compressed air and the correct size sockets to avoid damage to the tool and fasteners. Regularly lubricate the air motor with a few drops of pneumatic tool oil as per general pneumatic tool practice and follow routine maintenance to ensure consistent performance. When working on torque-critical fasteners, finish tightening with a torque wrench to achieve accurate clamp loads.
